Original application filed September 12, 1907, Serial No. 392,577.Divided and this application filed October 19, 1910. Serial No. 587,975.

To (121 whom it may concern Be it known that I, FRANK L. SESSIONS, acitizen of the United States, residing at Columbus, in the county ofFranklin and State of Ohio, have invented certain new and usefulImprovements in Winding Mechanisms, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to improvements in winding mechanisms, of akindparticularly adapted for use on electric mine locomotives.

In coal mines, operated on the room and pillar plan, it is the practiceto mine the coal at each of'numerous points. Afterthe masses areloosened the cars are distributed, one being taken to'each of the placesof mining. After they are loaded they are brought individually from therooms to the place 'where" they are coupled into trains or Electricallydriven locomotives trips are now largely employed for this gather ingpurpose. The ro omsand branch mine passageways leading to the rooms of\a mine are, as a usual rule, not equipped with a trolley wire or otherextended stationary conductor for supplying current to the locomotives.The tracks in these branch passageways and'rooms where the coal is cutand loaded, are temporary in character, and it is uneconomical to,provide trolley wire equipment over :these temporary tracks. The mainpassages of the mines are equipped with trolley wires. When thelocomotives leave these main entries to enter the rooms, current mustbe. supplied them by some means other than running contact of thetrolley wheel with the trolley wire. One of the means quite generallyemployed for this purpose, isa flexible conductor cable "which is woundupon a reel carried by the locomotive and is. attachable at its free endto a trolley wire at the point where the 1000- motive leaves thetrolley-equippedentry. Theobject of this invention is to provide such areel of an improved type and with an improved drive mechanism foroperat- I I theanl'es' by'gearing and this axle is connected b'y asprocket l3 and achain with a ingit.

As it is impossible to gain a clear conception of my invention withoutan understanding of the manner in which it isused scribe'rather fully anelectric locomotive of the type upon which a winding mechanism of myinvention is adapted to be used, and will show and describe the windingmechanism in position thereupon.

Figure 1 is a top plan view of a locomotive equipped with a windingmechanism embodying my invention. Fig; 2 is a side elevation of thesame. Fig. 3 is an end elevation of the winding devices and the frameparts supporting them, the side parts of the locomotive being shown. invertical section. Fig. 4 is a longitudinal sectional view of the windingdevices and associated locomotive parts Fig. 5 is afragmentary detailview' of-a part of the controlling device for one of the clutches.

The locomotive shown is formed with cast iron side frame elements 1 and2. These are preferably cast'integral from endto end. At their ends theyare connected to cross frame-pieces 3', 4, each ofthese also beingintegral from side to side. Each of the side pieces is formed with. tworectangular openings and in each opening there is fitted the journal-boxor bearing. for receiving the end of an axle. The axles are indicatedrespectively by 6 and 7. In the space between the axles there is mountedan electric motor 8.

to which current is usually supplied by trolley mechanism indicated by 9this being of any suitable character Just inside of the end cross piece3 of the-frame there is a chamber or space within which are located the.parts by which the motorman is enabled I to control the car andmanipulate various sprocket wheel on the other axle, so that power 18transmitted to both. The armature shaft of the motor is by means of thecouplingat 51 coupled to a shaft 46 which carries the worm 45. This wormengages with a worm wheel 15 on the axle 6. n the hub of the worm wheel15 there are clutch teeth 21 with which engage the teeth on an opposingclutch element 22. The latter is connected to the axle 6 by a feather orspline and can be moved into or out of engagement with the clutchelement at by means of the shifting devices comprisln'g fork'23, a

rock shaft 24 and a hand lever 25 near'the.

motorman, the shaft 24 being mounted in the bracket bearings at 26, 27.

The worm '45 above referred to is'mounted ontheshaft 46 and has thrustcollars 47 and 48, one on each side, provided with ball bearings. Theworm shaft 46 is supported inbearings 49 and 50011. the upper part ofthe gear case 30. The pitch of the thread of the worm 45 and of theteeth on the worm wheel 15 is such that the worm wheel'will drive theworm when the locomotive is coasting or drifting, as for example, whenthe current is cut out of the motor and the car is still advancing andits axle rotating.

. The reeling mechanism is carried by a frame indicated at 57, 58 and59. This frame isvsupported by bars 55, 56, which are secured to theside parts 1 and 20f the car wheel 66 on the end of the above mentionedworm shaft 46, through a chain 65 cpnnected to a sprocket wheel 64 onthe wormshaft 63. The casting 58 above referred to and a suppleinentalcasting 67 are so formed and secured together as to inclose the worm 62and the worm wheel 61, and moreover they are formed with bearings forthe shaft 63. The said castings 58 and 67 have-vertically extendingbosses or hubs 68 and 69 which furnish bearings for the vertical shaft60. The frame casting 57 is extended upward to a horizontal planesufliciently high and is formed with areel support 57 shaped to providepart of a ball race 70. In this are placed a-suitable number of steelballs 71. And on these a holder in the form of a cast iron ring 72 isarranged to rest, this having a circular groove to form the upperelement ofthe ball race. The upper surface of this holder or ring. 72 isflat as shown at 73, but

ts outer edge is provided with square teeth as-rat 74, to provide aratchet.

-: issec'ure .76 is a dpawl pivoted to the stud.75which to the upperpart ofthe frame piece or casting 57, this pawl being adaptedcounterweight also pivoted to the stud 75 and connected to the pawl 76by the bolt 78. The pawl has two active ends, one projecting to theright from the pivot 7 5 and the other to the left. It has also twopoints of attachment for the bolt 78 t0 the weight 77. By transferringthe weight and bolt from one side to the other of the center thedirection of. action of the pawl can be re versed. v

. 79 indicates the cable reel, preferably formed in the way shown andresting upon the flat surface 73 of the holder 72, and

adapted to revolve with the ring on the antifriction, balls at 71. When,however, the ring or holder 72 is prevented from revolving by the pawland ratchet, the reel can be revolved only b slidin or slipping on theface 73, which drms a rake to prevent the cable from being unwound morefreely than vThe upper shaft 83 is mounted in and projects upwardly fromthe top of the frame part or casting 57. Between this shaft and the reelthere is interposed a friction clutch. One member of this is a plate orflange 80 projecting inwardly from the periphery part of the reel. Theother member is composed .of-two plates or flanges 81 and 82 keyed tothe shaft 83, these overlapping-a central annular part of the flange orplate 80,- one lying above, the other lying below it; Frictionalengagement under pressure is produced by means of a spring '83 and theadjustable nuts 83 both above the clutch plate 82, the spring acting toclamp the plates 81 and 82 againstthe horizontal surfaces of the flangeor plate 80. The shaft 83 is shouldered just below the plate 81-toprevent the spring 83 from causing any'relative movement of plate 81 andthe shaft.

84 indicates the bearing for the shaft 83, it being central with theball race 70 and serving'to retain the reel and the clutches inproper'position. There is sufficient clearance to allow the entife shaft83 and the clutch plates, to rest under their weight on the ring 72 andthe balls 71. Shaft 83 pro jects below bearing 84 and upon itlthere isslidably mounted a righthand spiral jaw clutch 85 normally tending todropdowm ward a certain distance under its weight. 86 is a shifting formwhich engages with this and carries the weight of this clutch member.The fork .issecured to the rock shaft 87- which is mounted inbracketbearings 88 -89 formed on or secured to the stationary frame or-casting57.

90 is a-rocker arm or crank secured. tb the shaft 87, and 91 is ashifting rod connected 1 to. this rocker arm and extending to the I I I-.motormans end of the locomotive; At its to engage-the ratchet teethat74- '77 is a rear end this rod 91 rests on across bar 1 2 and is heldagainst it by the tension spring 9P. It is enlarged to form a latch 91"-so shaped that when the clutch 85 is in contact with the opposingclutch-element 93, this latch will rest on top of the cross bar 12*, butas the rod is drawn backward the bevel face of the latch will be forceddownward and backward by the spring 91 and the clutch member '85 will belifted to the frame casting 57.

The shaft 60, above described, carries at its upper end a right-handspiral jaw clutch member 92. Between this and the aforesaid clutchmember 85- there is interposed a clutch ring 93 having two sets ofclutchteeth, a set of right-hand teeth on its upper face and a set ofleft-hand teeth on its lower face. It may be clamped to either of theparts 85 and 92 by clamping ring 94 having inwardly projecting flangeswhich correspond to suitable grooves in the three clutch members.

By means of this clamping ring the clutch can 'be readily converted fromright-hand to left-hand or from left to right as may be desired.

The flange 80, of the reel 79, also serves as a support for the ring ofinsulation at 95 to which is secured the collector ring 96. The electriccable (for the winding of which the reel is employed) has the inner endof its conductor electrically connected to this collector ring 96, theend part of the cable being passed through the aperture in the reelperiphery at 96 and a binding lug 97 being provided for firmly fasteningthe end of the metallic conductor. From the collector ring 96, thecurrent is taken to a stationary circuit terminal at 100 by means of thecontact finger 99, carried by the insulating block 98 and supported uponthe stationary frame casting 57 in such way as to press against thecollector ring. The cable can be taken to and from the reel as it is.being wound or unwound from points along the track either in front of orbehind the locomotive. At each end of the locomotive there are mountedupon the side frames 1 and 2 suitable guide rollers 1 and 2 to properlydirect the cable as it is being taken up or paid out.

The devices above described are for the purpose of conducting current tothe electric apparatus on the car when the trolley mechanism is out ofoperation. For instance, when isolated cars are to be taken out of themine rooms after they have been loaded and gathered on the tracks in theentries for making up trains, and when these cars are at a distance fromthe main currentsupplying wires the cable is availed of for actuatingthe motors on the locomotives.

The operation of the electric cable reel is as follows: The cable havingbeen wound on the reel in the proper direction, it is desired to takethe locomotive into a room where there is no trolley wire. The. free endof the cable is connected with the trolley wire by appropriateattachments, and the trolley is locked in such a position as to be outof the way. The motor now receives current through the cable and thecollector mechanism on the reel, and may be run into the room, the cableunwinding as the locomotive proceeds. As the pawl 76, engaging theratchet 74, .prevents the revolution of the brake ring 72, the reel 79will slide on the face 73 of the brake ring 72, the retarding effect ofwhich will prevent too rapid unwinding of the cable, and tend to hold itoff the ground. Before starting to return, the operator pushes the rod91 forward until the latch 91 rests on 'top of the cross bar 12*. Thiswill cause the clutch 85 to engage with the clutch 93, and, when thelocomotive starts, the friction disks 81 and 82 will cause the reel torevolve in the winding direction. As the pawl 7 6 does not prevent thering 72 from revolving in this direction, the whole device revolves onthe ball bearings 71 without unnecessary friction. The proportions ofthe reel and its driving members are such that the tendency is for thereel to revolve faster than the cable will wind. This is compensated forby the slipping of the friction clutch members 81 and 82 against theflange 80, the pressure of the spring 83 being so adjusted as to keep adesirable tension on the cable. When the locomotive reaches the entry,and the cable is disconnected from the trolley wire, the clutch 85should be thrown out to prevent unnecessary wear on the friction members80, 81 and 82; but, if the direction of the locomotive is reversed, theclutch member 85 will climb on the face of the clutch member 93, thusrocking the arm 90, which will push the rod 91 forward until the latch9.1 slips over the edge of the cross bar 12, and the spring 91 willforce the rod clear back and insure the clutch 85 clearing the teeth on93.

If for any reason it is desired to use the locomotive in a part of themine where it will be necessary to enter the rooms rear end first, theclamping ring 9% may be shifted to clamp thering 93 to the clutch 85,making a left-hand clutch instead of a righthand; the counterweight 77shifted to the other side of the pawl 7 6; and the cable entirelyunwound and rewound in the opposite direction; after which the operationis as before.
